It’s the beginning of Lent in the isolated Somerset village of Oakham, some time in the late fifteenth century. As the villagers prepare for their forty days of penance, a dead man is seen in the river. By the time rescuers come to help, the body has been swept away, but a fragment of clothing confirms its identity: Tom Newman, a prosperous, curious dreamer, and one of the few villagers to have ventured beyond the parish boundaries. The rains have been falling heavily and the riverbanks are thick with mud. He could have slipped in. But the question remains: was it misadventure or murder? As the small community huddles under bleak skies and heavy rains, the priest John Reve struggles to comprehend the mystery, dogged by the interference of the visiting dean, weighed down by the confessions of his parishioners, and troubled by the way that Newman’s death threatens to pull apart a whole network of secrets, doubts and obligations that bolster Oakham against the outside world.
